藏獒皮肤成纤维细胞培养与生物学特性观察

Abstract

Abstract: In order to study biological characteristics of Tibetan Mastiff somatic cells and preserve genetic resource, two fibroblast cell strains from Tibetan Mastiff were established by tissue culture. In vitro culture cell morphology, hyperplasia ability and some biological characteristics were researched. Tibetan Mastiff cells in vitro culture appeared typical morphology of fibroblast cells, grew well and had strong hyperplasia ability. Population doubling time of the cells was 46.1 h. Vimentin expression in the cells was confirmed by immunofluorescence staining. The rate of F5 cells with normal diploidy (2n=78) was 91.4%. Moreover, longer X chromosome belonged to submetacentric chromosome, but Y chromosome did telocentric chromosome. Tibetan Mastiff cell strains eslablished in the study offered the materials for the Tibetan Mastiff somatic cell nuclear transfer research.

Key words: Tibetan Mastiff; cell culture; fibroblast cell; immunofluorescence staining
